Spinal Nerve Root Injection

Nerve Root Injection (NRI): This is a diagnostic and therapeutic injection. Both a strong anesthetic and steroid are used and injected around the nerve and into the epidural space.

 

Overview of the nerve root injection procedure

Here’s what to expect during a lumbar nerve root injection procedure:

  • You will lie face down, with a pillow underneath your abdomen.
  • The injection area is cleaned and numbed before the injection.
  • Using fluoroscopic (X-ray) guidance, your physician will determine the appropriate path for the needle.
  • Your doctor will insert a thin needle to a point immediately behind the nerve root.
  • Next, your doctor will inject a small amount of contrast dye to make sure that the medication will flow exactly where intended.
  • Then, your physician will inject a small amount of anesthetic, steroid, or a combination of both, depending on the procedure’s purpose.
  • During the injection, you may feel a sensation of pressure in the neck or arm. This typically disappears in a few moments.
  • After the procedure, you’ll spend 20 to 30 minutes in the recovery area.
